A 13,500 kg railroad freight car travels on a level track at a speed of 4.5ms. It collides and couples with a 25,000 kg second car, initially at rest and with brakes released. (a) What is the speed of the two cars after collision? (b) What is the impulse experienced by each car? (c) If the collision takes 3 seconds to occur, with what force did the collision occur?
